The image shows four cloud regions, two for Azure on one side of the image and two for Oracle Cloud Infrastructure on the other side. Positioned between the Azure regions and the OCI regions are two instances of the ODSA control plane. One connecting Azure region 1 to OCI region 1, the other connecting Azure region 2 to OCI region 2.

Each Azure region contains an instance of Azure VNet,which itself contains a subnet comprising a compute instance. The OCI regions contain a customer VCN, within which is a subnet labeled mc-customer-subnet-NL-1 and contains an Oracle database instance. Each ODSA control plane contains a multicloud NetworkLink container comprising an Azure ExpressRoute instance and an OCI FastConnect instance.

Traffic travels between the regions through the ODSA control planes. The OCI regions communicate either through remote peering or via Data Guard. Access to the OCI VCNs, both from the ODSA control planes and between the OCI regions themselves, is through a dynamic routing gateway
